Hello everyone! I'm installing bead board panels on the upper part of a wall. I planned on removing all window and shelving trim and the top part of the chair rail and just hiding the panels with the existing trim but ran into a problem where the in wall shelving unit is. If I remove the trim and put back on top of the panels, there will be a gap between the trim and the inside of the shelving unit/windows. My other thought was to leave all of the trim and just bring panels up to them and add some 1/4 round along the trim and on top of the chair rail. Hopefully the pics are helpful (pictured is the top of the chair rail where it meets the right side of the shelving unit)
1.) Leave the trim in place and cut the panels 'net' to the trim. You could then close the juncture with a little caulk if you are painting everything.
2.) You could also remove the trim and extend the jambs with a piece of lattice, install the panels up to the lattice. That seam would then be hidden under the trim when it is reinstalled. Then paint/stain the small edge of the lattice that is exposed.
